Abstract (en)
[origin: EP0128575A2] The protector for threads which are provided at the end of a tube is constructed essentially as a sleeve or cap 10 which, in the case of protecting external threads, has threaded portions 16 on inwardly projecting partial surfaces, which threaded portions can be screwed to the thread to be protected. In the case of the internal thread requiring protection, the protective sleeve 19 is provided with outwardly directed projections 22, on which threaded portions 23 are constructed. The threaded portions constructed on partial surfaces of the protector are produced by embossing or hammering, the material of the protective sleeve being deformed against a tool which has a thread corresponding to the end of the tube to be protected. Due to the permanent deformation of the shell of the protective sleeve or the protective cap, the thread on the tool is reproduced on projecting partial surfaces. <IMAGE>
